The .40S&W is quite a capable cartridge. I don't think that any one handgun caliber or bullet is perfect, but it's definitely at the top of the list of widely available choices.

I use 180 gr. Hydra Shoks in my carry pistol. I've never had to use it in self-defense, thankfully, so I rely on LEO experience andballistics studies (primarily from the FBI and affiliates) for information. Myopinion ofthe Hydra Shoks has always been good. The muzzle flash is fairly good in low light, it feeds perfectly, and it shoots more accurately from the bench than I'm capable of unsupported.

One problem I've heard about on more than one occasionis the tendency of theHP cavity to clog, particularly when fired through heavy (i.e. leather) clothing or multiple layers. This is something to consider very seriously, especially during the winter months.

My preferences in terms of performance are: 1) shot placement; 2) penetration; and 3) expansion. For this reason I would prefer the Hydra Shoks even against a heavily clothed adversary because of its penetration capability.

So that's one man's opinion. Good luck out there, and stay safe!
